What is hardware? A topic that will answer all your questions

What is hardware?

Hardware, or what is also called computer hardware, is all the tangible physical components that make it up, which after connecting them we have a stand-alone computer in terms of hardware, and of course, in the case of a desktop computer, all these physical components are collected inside a box called “case” so as not to be exposed to external factors that It may cause damage from dust, moisture and other factors affecting the electronic parts.

Among these basic hardware components, we mention:
  • Motherboard
  • Power Supply
  • Processor
  • Processor Socket
  • Northbridge
  • Graphics card
  • Southbridge
  • Ram
  • Ram Slots
  • Bios
  • Monitor
  • Keyboard
  • Touchpad
  • Wireless card
  • Sound card
  • Hard disk drive
  • CD/DVD Rom reader
  • case
and other physical components that makeup computer hardware.

Hardware Function

In the following, we will explain the function of each hardware component separately.

1. Motherboard

It is the most important piece in the computer and on it, other pieces that are considered secondary are connected and connected, so it is called the motherboard. Its name indicates its work. It connects all the pieces and transfers data and digital information between these pieces. Of course, there are many boards and what makes them different from each other is It has their design and support for multiple electronic components. For example, there is Motherboard that supports most processors, there are others that only support one or two processors, and so on.

2. Processor

The processor is a very complex and complex integrated circuit, elaborately designed and highly accurate, and that is due to the task entrusted to it, and its role is to process information automatically and very quickly. In any electronic device, especially a computer or computer, especially if its cache memory is also large in terms of capacity.

3. Northbridge

The Northbridge is a large chip that connects to a computer's central processing unit via buses and controls memory interaction, the activities of the Peripheral Component Interconnect (PCI) bus, RAM, and the graphics acceleration port (AGP). The Northbridge connects to the processor using the front-side bus, or FSB and is one part of the Northbridge / Southbridge combination. So, in summary, the northbridge connects the processor, random memory, graphics card, and the southbridge.

4. Southbridge

Southbridge includes all the controllers for the ports on the motherboard, that is, when it comes to the input and output ports, as well as the hard disk, disk reader, floppy disk, bios, and so on, in addition to that it handles the input/output (I / O) functions of the chipsets.

5. Graphic card

It has many names such as the graphics card, and the game card, and it is also known as the graphics adapter, graphics controller, graphics acceleration card, and other titles. It is considered one of the most important components of a computer. It is a type of video card installed in most computers to display graphic data. It is classified as a large computer chip. A graphics card provides a display of images by processing and executing graphic data using advanced graphic technologies, features, and functions.


RAM, or so-called random access memory, is a complex and complex electronic chip that stores data randomly, quickly, and very frequently, knowing that this storage is temporary and not final, and this is because this type of memory constantly needs to be supplied with energy to maintain On the data inside it, which is unlike the ROM, which retains data despite the absence of electric current.

7. Bios

The BIOS is an electronic component that can be classified into an integrated chip, an 8-legged ISI that is the same as a MOSFET in terms of shape and number of legs but is rather large compared to a MOSFET. The BIOS is the carrier of the firmware or flash file that has the bin extension. An abbreviation for Binary. It is a small piece, but it is very important, as it is a chip that contains the data for booting the motherboard and operating the device.

What is hardware as a service?

While it is common for individuals or businesses to purchase computers and then replace or upgrade them periodically, they may also rent physical and virtual hardware from their service provider. The provider is then responsible for updating the hardware, including the various hardware and software that runs on them. This is known as the Haas model.

The main advantage of HaaS is that it reduces the cost of purchasing and maintaining hardware, enabling organizations to move from a capital expenditure budget to an often cheaper operating expense budget. Also, since most HaaS offerings are based on a pay-as-you-go model, it makes it easier for organizations to control costs while still having access to the hardware they need for operational and business continuity.

In Haas, the hardware of the Managed Service Provider (MSP) is installed at the customer site. The Service Level Agreement (SLA) sets out the responsibilities of both parties.

Customers may pay a monthly fee to use the MSP Equipment, or its use may be included in the MSP fee structure for installing, monitoring, and maintaining the Equipment. Either way, if hardware fails or becomes outdated, MSP is responsible for repairing or replacing it.

Depending on the terms of the Service Level Agreement (SLA), turning off devices may include erasing private data, physically destroying hard drives, and ensuring that old equipment is legally recycled.
